[ background of the invention ]

Gas cookers are common kitchen appliances, and the burner flame of the burner is roughly divided into a top fire and a side fire. In either form of fire, the flame direction, once fixed, is generally not changeable.

However, for small milk or soup pots of small size, the user always wants the flame to converge as much as possible on the pot. For relatively large pans, without requiring a temperature profile, it is desirable that the area covered by the flame be as large as possible.

Unless otherwise supported by sufficient evidence, the prior art described herein is not meant to be an admission that such prior art is widely known to those of ordinary skill in the art to which this application pertains prior to the filing date of the present application.

[ summary of the invention ]

An object of the present invention is to provide an improved burner for a gas cooker, a burner including the burner, and a gas cooker including the burner, in view of at least one of the above technical problems.

Another object of the present invention is to provide a burner for a gas range in which flame distribution can be changed.

An embodiment of the invention relates to a burner of a burner for a gas stove. The burner of the burner for the gas stove comprises a base body, wherein a gas cavity for containing gas is formed in the base body, a first fire outlet and a second fire outlet are formed in the base body, the radial distances from the first fire outlet to the center of the base body are different from the radial distances from the second fire outlet to the center of the base body, the burner further comprises at least one core piece, a gas channel is formed in the core piece, and the gas channel is communicated with the gas cavity in the use state of the core piece; the core piece and the seat body have a first relative position relation and a second relative position relation, when the core piece is placed on the seat body and the core piece and the seat body are in the first relative position relation, the gas channel is communicated with the first fire outlet, and the gas channel is blocked with the second fire outlet; when the core piece is placed on the seat body and the core piece and the seat body are in the second relative position relationship, the gas channel is communicated with the second fire outlet, and the gas channel is blocked from the first fire outlet.

The technical effect of the above scheme is that the burner can be fired from the first fire outlet or the second fire outlet by adjusting the relative position relationship between the core piece and the base body, the burner of one burner has different flame distributions, and various requirements of users can be met.

The invention provides a technical scheme with different technical concepts, and the technical effect of the technical scheme exceeds the level of the prior art.

Wherein, in the above-mentioned scheme, the relative position that first fire outlet was put out the fire hole and is different with the second, as required, the first fire outlet also can be different with the second fire outlet's play fire direction and/or aperture.

When the core piece and the seat body are in a first relative position relationship, the gas channel is communicated with the first fire outlet and is blocked from the second fire outlet; when the core piece and the seat body are in a second relative position relationship, the gas channel is communicated with the second fire outlet and is blocked from the first fire outlet. The scheme can change the flame distribution of the burner, and the change of the flame distribution is not limited to two types of flame cohesion and flame full burner distribution, but can be changed in more ways, such as in one embodiment, three conversion forms of flame distribution of a combustor, namely flame cohesion, flame outward spraying and flame full burner distribution; in another embodiment, the flame distribution of the burner is in the form of flame cohesion, flame external flame spray, and alternating internal flame convergence and external flame spray. Therefore, the scheme can enable the change of the flame distribution of the burner to be more obvious, the change types are more, the form is more flexible, and various cooking requirements of various users can be met.

Wherein the first relative positional relationship and the second relative positional relationship relate to at least a relationship of position and direction.

In addition, in some embodiments, the central area of the burner may be provided with a small size central burner.

In one or more embodiments, the core member and the seat body further have a third relative positional relationship, and when the core member is placed on the seat body and the core member and the seat body are in the third relative positional relationship, the gas channel is communicated with both the first fire outlet and the second fire outlet. It can be seen that this scheme further has the advantage that the change that furnace end flame distributes is abundanter, more nimble, and the furnace end of combustor not only can have flame cohesion, flame outward spout can also have this kind of form of flame full furnace end distribution.

In one or more embodiments, the first fire outlet and the second fire outlet are located at the same level. With this arrangement, when the gas passage is communicated with one of the first fire outlet and the second fire outlet and the core member and the seat body are switched to the relative position, the gas passage can be directly communicated with the other of the first fire outlet and the second fire outlet. The improvement of this embodiment can make things convenient for gas channel's design structurally, simplifies the structure of furnace end.

In one or more embodiments, the burner includes a plurality of independent gas passages, and each gas passage corresponds to one first fire outlet and one second fire outlet. Just because this scheme includes a plurality of independent gas passage, this scheme further has the advantage that, can adjust the flame distribution of furnace end more in a flexible way, the flame of furnace end can have the distribution of more various forms moreover, and then satisfies various demands of various users. Wherein "said burner comprises a plurality of separate said gas channels" is to be understood that at least the outlet section of each gas channel is mutually independent, i.e. at least the section of the gas channel where the first and second fire holes meet is mutually independent. In some embodiments, the gas passages include inlet and outlet sections, the inlet sections of each gas passage communicating with each other to form an annular passage, and the outlet sections of each gas passage being independent of each other. In other embodiments, the gas passages comprise an inlet section and an outlet section, each gas passage being independent of the other from the inlet section to the outlet section.

It should be noted that the phrase "one first fire outlet and one second fire outlet are provided for each gas passage" does not mean that each gas passage must be in communication with one first fire outlet and one second fire outlet. When the core piece and the seat body are in the first relative position relationship, the gas channel is communicated with the corresponding first fire outlet; when the core piece and the seat body are in the second relative position relationship, the gas channel is communicated with the corresponding second fire outlet. In other embodiments, when the core member and the seat body are in the third relative position, the gas channel is communicated with the corresponding first fire outlet and the second fire outlet.

In one or more embodiments, the burner includes an annular core member, the housing includes an annular receiving groove communicating with the first fire outlet, the second fire outlet and the gas chamber, respectively, and the core member is adapted to be received in the receiving groove and rotatable relative to the receiving groove. Thus, the core member and the seat body have a first relative positional relationship and a second relative positional relationship.

In one or more embodiments, a plurality of the gas passages are provided in the core, each of the gas passages extending in a Y-shape or a T-shape in the core.

In one or more embodiments, the first fire outlet and the second fire outlet are distributed in a staggered manner in the radial direction of the seat body. Therefore, when the core piece and the seat body are in a first relative position relation, the gas channel is communicated with the first fire outlet and is blocked from the second fire outlet; and rotating the core piece to switch the core piece and the seat body from the first relative position relation to the second relative position relation, so that the gas channel is communicated with the second fire outlet and is blocked from the first fire outlet.

In one or more embodiments, the burner includes an annular core, the base includes an inner ring provided with the first fire outlet and an outer ring provided with the second fire outlet, the outer ring is disposed at the periphery of the inner ring and surrounds the first fire outlet and the second fire outlet to form the gas chamber and a receiving groove for receiving the core, the receiving groove is communicated with the first fire outlet, the second fire outlet and the gas chamber, and the inner ring is rotatable relative to the outer ring, so that the core and the base have the third relative position relationship. The flame distribution of the furnace end of the scheme has three forms, namely, only a first fire outlet hole on the inner ring body emits fire, only a second fire outlet hole on the outer ring body emits fire, and the fire outlet holes on the inner ring body and the outer ring body emit fire.

In one or more embodiments, the side walls of the inner ring and the outer ring facing each other are respectively formed with a protruding step portion, and in the use state of the seat body, the step portions are used for supporting the core member. Therefore, through simple step portions, the inner ring body and the outer ring body surround, the gas cavity and the accommodating groove for accommodating the core piece are formed simultaneously, and the gas cavity is communicated with the accommodating groove, so that the structural design is extremely simplified, the relative position relation between the core piece and the seat body is conveniently adjusted, and more flame distribution forms are obtained.

In one or more embodiments, the burner includes a plurality of cores, the housing includes a plurality of receiving grooves for receiving the plurality of cores, each receiving groove communicates with one of the first fire outlet, one of the second fire outlet, and the gas chamber; wherein one of the core pieces is disposed corresponding to one of the receiving grooves. In this embodiment, each of the core members is independent, so that the relative position relationship between each of the core members and the seat body can be adjusted by a user, thereby enabling the flame distribution of the burner to be adjusted more freely and flexibly.

In one or more embodiments, one first fire outlet and one second fire outlet, which are communicated with the same accommodating groove, at least partially overlap in the radial direction of the seat body.

In one or more embodiments, the core member is horizontally rotated by 180 degrees after being separated from the holder body and then placed in the receiving groove, so as to switch between the relative positional relationship of the core member and the holder body.

In order to ensure that the burner does not leak fire at the location where fire should not be discharged, in one or more embodiments, the base body is circular or annular, the receiving groove is a square groove and a plurality of receiving grooves are distributed along the circumferential direction of the base body, the core piece has a shape matching the receiving groove, and when the core piece is received in the receiving groove, the core piece closes the receiving groove, so that the gas in the gas chamber flows out only from the first fire outlet or the second fire outlet.

In one or more embodiments, the gas passage extends linearly in the core member and is inclined with respect to one wall surface of the core member, or the gas passage extends in an L-shape in the core member. Thus, when the gas channel is communicated with the first fire outlet and is blocked with the second fire outlet, the core piece is taken up and horizontally rotated by 180 degrees and then placed in the accommodating groove, and the gas channel is naturally communicated with the second fire outlet and is blocked with the first fire outlet.

In one or more embodiments, in a use state of the burner, each core member and the seat body are in the first relative position relationship; or, each of the core members is in the second relative positional relationship with the seat body; or the core pieces which are in the first relative position relation with the seat body and the core pieces which are in the second relative position relation with the seat body are distributed in a staggered way. Of course, the user can have more flame distribution forms according to the needs, because each core piece is independent, and the relative position relationship between the core piece and the seat body can be independently changed.

Another aspect of the embodiments of the present invention relates to a burner of a gas stove, which includes the burner according to any one of the above embodiments.

In one or more embodiments, the burner of the gas stove includes a burner seat, and the burner is disposed on the burner seat.

Yet another embodiment of the present invention relates to a gas range including the burner of the gas range as described above.

It should be pointed out that the features of the dependent claims can be combined with each other and with the features of the independent claims in any way without departing from the inventive concept.

The burner head 1 of the gas range burner of the present embodiment has a ring shape, and includes a ring-shaped base body 10 and a ring-shaped core member 20 placed on the base body 10.

A gas chamber 11 for accommodating gas and a receiving groove 12 for accommodating the wick 20 are formed in the housing 10 (see fig. 4). Wherein, holding tank 12 is an annular groove, and holding tank 12 and gas chamber 11 are linked together. The core 20 is adapted to be received in the receiving groove 12 and rotatable relative to the receiving groove 12.

In the present embodiment, the seat body 10 actually includes an inner ring body 10a and an outer ring body 10b, and the inner ring body 10a and the outer ring body 10b are connected by the connecting rib 14 to form the seat body 10. The side walls of the inner ring body 10a and the outer ring body 10b facing each other are formed with protruding step portions 13, respectively. In the use state of the seat body 10, as shown in fig. 2, the step portion 13 is used to support the core member 20.

The base 10 is provided with a first fire outlet 100 and a second fire outlet 200, and the radial distances from the first fire outlet 100 and the second fire outlet 200 to the center of the base 10 are different. Specifically, in the present embodiment, the first fire outlet 100 is located at the inner ring of the seat 10, and the second fire outlet 200 is located at the outer ring of the seat 10. The accommodating groove 12 is respectively communicated with the first fire outlet 100, the second fire outlet 200 and the gas chamber 11.

As shown in fig. 4, the first fire outlet 100 and the second fire outlet 200 are located at the same level. As shown in fig. 3, the first fire outlet 100 and the second fire outlet 200 are arranged in a staggered manner in the radial direction of the base 10.

In this embodiment, as shown in fig. 1, a flame stabilizing groove 101 is further disposed between any two adjacent first fire outlet holes 100, and a flame stabilizing groove 201 is disposed between any two adjacent second fire outlet holes 200. The

flame stabilizing grooves

101 and 201 are not communicated with the gas cavity 11, if the first fire outlet hole 100 or the second fire outlet hole 200 has gas to flow out, the gas will flow into the

flame stabilizing grooves

101 or 201, and when the burner is in operation, flame is formed at the

flame stabilizing grooves

101 or 201. The flame formed by the flame stabilizing grooves is used for stabilizing the flame combustion of the corresponding first fire outlet or the second fire outlet.

As shown in fig. 2, a plurality of independent gas passages 21 are formed in the core member 20, the gas passages 21 include inlet sections 211 and outlet sections 212, the inlet sections 211 of each gas passage 21 communicate with each other to form an annular passage, and the outlet sections 212 of each gas passage 21 are independent from each other. Each gas channel 21 is T-shaped in radial section through the core 20. Each gas channel 21 corresponds to one first fire hole 100 and one second fire hole 200. In the use condition of the cartridge 20, the gas passage 21 communicates with the gas chamber 11.

The core 20 of the present embodiment has a first relative positional relationship and a second relative positional relationship with the holder body 10.

As shown in fig. 2, the burner 1 shown in fig. 2 is a cross-sectional view when the core 20 and the housing 10 are in a first relative positional relationship. When the core 20 is placed on the seat body 10 and the core 20 and the seat body 10 are in the first relative position relationship, the gas channel 21 is communicated with the first fire outlet 100, and the gas channel 21 is blocked from the second fire outlet 200. The dashed line with arrows in fig. 2 indicates the flow direction of the gas, and the gas in the gas chamber 11 flows out from the first fire outlet 100 through the gas passage 21. At this time, the burner 1 has only the first fire outlet 100 located in the inner ring for the gas to flow out, and after being ignited, the gas forms a flame. The second fire outlet holes 200 located at the outer ring have no gas outflow, and thus flame cannot be formed. When the furnace end 1 works, only the inner ring has flame, and at the moment, the flame of the furnace end 1 is cohesive and is suitable for heating cooking utensils with smaller diameters, such as milk pots, small frying pans and small soup pots.

It should be noted that the dotted line with an arrow in fig. 2 is only a simple illustration of the flowing direction of the gas, and does not represent the actual fire direction of the first fire outlet 100, and in fact, the fire direction of the first fire outlet 100 can be adjusted by adjusting the angle of the first fire outlet 100, such as being inclined upwards.

When the core 20 is placed on the seat body 10 and the core 20 and the seat body 10 are in the second relative position relationship, the gas channel 21 is communicated with the second fire outlet 200, and the gas channel 21 is blocked from the first fire outlet 100 (not shown). At this time, only the second fire outlet 200 of the burner 1 located at the outer ring has the gas flowing out, and the gas forms a flame after being ignited. The first fire outlet 100 located at the inner ring has no gas outflow, and no flame is formed. When the furnace end 1 works, only the outer ring has flame, and at the moment, the flame of the furnace end 1 is sprayed outwards, so that the furnace end is suitable for heating cooking utensils with larger diameters, such as large woks.

In this embodiment, when the core 20 and the seat body 10 are in the first relative positional relationship, the core 20 and the seat body 10 can be in the second relative positional relationship by rotating the core 20. Then, the core 20 is rotated back to the first relative position relationship between the core 20 and the seat 10. The first fire outlet 100 and the second fire outlet 200 are arranged in a staggered manner in the radial direction of the base 10. When the core 20 and the holder body 10 are in the first relative position relationship, the gas passage 21 is communicated with the first fire outlet 100, and the gas passage 21 is blocked from the second fire outlet 200. When the core 20 is rotated to bring the core 20 into a second relative positional relationship with the housing 10, the gas passage 21 communicates with the second fire exit hole 200, and the gas passage 21 is blocked from the first fire exit hole 100.

The degree of rotation of the core 20 may be specifically determined according to the distribution of the first fire holes 100 and the second fire holes 200. To alert the user, corresponding position markings may be provided on both the housing and the core to alert the user that the core 20 is in a first relative positional relationship with the housing 10 and the core 20 is in a second relative positional relationship with the housing 10, respectively.

In order to maintain the core 20 and the housing 10 in the respective relative positional relationship, positioning structures, such as positioning studs and positioning holes, may be provided at corresponding positions on the housing and the core. When the core 20 is placed on the seat body 10 and the core 20 and the seat body 10 are in the first relative position relationship, the core 20 can be rotated by a certain angle after being removed from the seat body 10, and then the core 20 is placed on the seat body 10, so that the core 20 and the seat body 10 are in the second relative position relationship.

Next, a furnace end 2 of a second embodiment of the invention is described, please refer to fig. 5 to 8, wherein fig. 5 is a perspective view of a base body of the second embodiment of the invention; fig. 6 is a sectional view of a housing according to a second embodiment of the present invention; fig. 7 is a cross-sectional view of the burner of the second embodiment of the present invention when the core member and the base body are in a first relative position relationship; fig. 8 is a cross-sectional view of the burner of the second embodiment of the present invention when the core and the base are in a third relative position.

The same or similar structures of this embodiment and the first embodiment use the same or similar reference numerals, and the functions and actions thereof are the same or similar, and are not described again here. Unlike the first embodiment, the holder body 30 of the present embodiment includes an inner ring body 30a provided with the first fire outlet 100 and an outer ring body 30b provided with the second fire outlet 200, the outer ring body 30b is disposed on the periphery of the inner ring body 30a and surrounds the inner ring body 30a to form a gas chamber 31 and a receiving groove 32 for receiving the wick 20. The accommodating groove 32 is respectively communicated with the first fire outlet 100, the second fire outlet 200 and the gas chamber 31. The inner ring 30a can rotate relative to the outer ring 30b such that the core member 20 and the seat body 30 have a third relative positional relationship.

The side walls of the inner ring 30a and the outer ring 30b facing each other are respectively formed with a protruding step portion 33, and as shown in fig. 7 and 8, the step portion 33 is used to support the core member 20 in the use state of the seat body 30.

As shown in fig. 7, similar to the previous embodiment, when the core 20 is placed on the seat body 30 and the core 20 and the seat body 30 are in the first relative position relationship, the gas channel 21 is communicated with the first fire outlet 100, and the gas channel 21 is blocked from the second fire outlet 200. The dashed line with arrows in fig. 7 indicates the flow direction of the gas, and the gas in the gas chamber 31 flows out from the first fire outlet 100 through the gas passage 21. When the furnace end 2 works, only the inner ring has flame.

When the core 20 is placed on the seat 30 and the core 20 and the seat 30 are in the second relative position, the gas channel 21 is communicated with the second fire outlet 200, and the gas channel 21 is blocked from the first fire outlet 100 (not shown). At this time, only the second fire outlet 200 of the burner 1 located at the outer ring has the gas flowing out, and the gas forms a flame after being ignited. When the furnace end 2 works, only the outer ring has flame.

As shown in fig. 8, when the core 20 is placed on the seat body 30 and the core 20 and the seat body 30 are in a third relative position, the gas channel 21 is communicated with the first fire outlet 100 and the second fire outlet 200. The dashed lines with arrows in fig. 8 indicate the flow direction of the gas, and the gas in the gas chamber 31 flows out from the first fire outlet 100 and the second fire outlet 200 through the gas passage 21. When the furnace end 2 works, the inner ring and the outer ring are both provided with flames.

In the present embodiment, when the core 20 is placed in the holder body 30, by rotating the core 20, the first relative positional relationship and the second relative positional relationship between the core 20 and the holder body 30 can be switched. By rotating the outer ring 30b or the inner ring 30a, the core 20 and the holder body 30 can be switched from the first relative positional relationship or the second relative positional relationship to the third positional relationship.

This embodiment has the further advantage over the first embodiment that the burner 2 can have a more distributed form of flame.

It should also be noted that the dotted lines with arrows in fig. 7 and 8 are only a simple illustration of the gas flow direction and do not represent the actual final fire direction, and in fact, the fire direction can be adjusted by adjusting the angles of the first fire outlet 100 and the second fire outlet 200.

Please refer to a furnace end 3 of a third embodiment of the present invention, please refer to fig. 9 to 13, wherein fig. 9 is a perspective view of the furnace end of the third embodiment of the present invention; fig. 10 is a perspective view of a seat body according to a third embodiment of the invention; fig. 11 is a cross-sectional view of the burner of the third embodiment of the present invention when all the core members and the holder body are in the first relative positional relationship; fig. 12 is a cross-sectional view of the burner of the third embodiment of the present invention with all the core members and the holder body in a second relative positional relationship; fig. 13 is a cross-sectional view of a portion of the core member and the base member in a first relative position relationship and a portion of the core member and the base member in a second relative position relationship in a burner according to a third embodiment of the present invention.
